LB1830M-TE-L-E Equivalent & Substitute Parts

Part Overview

The LB1830M-TE-L-E is a brushed DC motor driver IC manufactured by onsemi, designed for applications requiring fully integrated control and power stage functionality. This surface mount device operates across a 3V to 9V supply range with 500mA output current capability and half-bridge dual output configuration. The product is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LB1830M-TE-L-E is determined by the following core parameters:

• Motor driver function with fully integrated control and power stage
• Brushed DC motor application support
• Half-bridge dual output configuration
• Parallel interface control
• Bipolar technology implementation
• Output current capability of 500mA or greater
• Supply voltage range encompassing or exceeding 3V to 9V
• Load voltage compatibility with 3V to 9V range

Three substitute parts meet these criteria with varying trade-offs in packaging, voltage range, and current capacity. All substitute parts maintain the essential functional architecture while offering different form factors and enhanced electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are active products with RoHS compliance certification, providing long-term availability and regulatory alignment advantages over the obsolete LB1830M-TE-L-E.

TA7267BP(O) offers the highest output current at 1A and operates across an extended voltage range of 6V to 18V. This part is suitable for applications requiring higher current delivery. The through-hole 7-SIP package requires PCB redesign if surface mount form factor is mandatory.

TA7291FG(O,EL) maintains surface mount compatibility with a 16-BSOP package and provides the widest supply voltage range of 4.5V to 20V. Output current is specified at 400mA, which is lower than the original 500mA specification. This part includes integrated heat tabs for improved thermal management.

TA7291SG(O,J) provides identical electrical specifications to the TA7291FG(O,EL) but uses a through-hole 9-SIP package. This configuration is appropriate for legacy PCB designs utilizing through-hole mounting.

Selection between these alternatives depends on PCB mounting technology constraints and application voltage requirements. All three parts satisfy the core functional requirements of the LB1830M-TE-L-E.

Frequently Asked Questions (FAQ)

Q: Can the TA7267BP(O) substitute for the LB1830M-TE-L-E in a 3V to 9V application?

A: The TA7267BP(O) operates across 6V to 18V supply range. Applications requiring operation below 6V are not compatible with this substitute. Verify minimum supply voltage requirements before selection.

Q: What is the impact of the 400mA output current specification on the TA7291 series compared to the original 500mA?

A: The TA7291FG(O,EL) and TA7291SG(O,J) are rated at 400mA output current versus the LB1830M-TE-L-E specification of 500mA. Applications requiring sustained output currents exceeding 400mA must use the TA7267BP(O) rated at 1A.

Q: Are there package compatibility considerations for PCB redesign?

A: The LB1830M-TE-L-E uses a 10-LSOP surface mount package. The TA7291FG(O,EL) uses a 16-BSOP surface mount package with different pin count and spacing, requiring PCB layout modification. The TA7267BP(O) and TA7291SG(O,J) use through-hole packages, necessitating significant PCB redesign if surface mount technology is required.

Q: What are the thermal management differences between substitute options?

A: The TA7291FG(O,EL) includes integrated heat tabs for enhanced thermal dissipation. The TA7267BP(O) and TA7291SG(O,J) do not specify integrated heat management features. Thermal analysis is required for high-current or high-ambient-temperature applications.

Q: Do all substitute parts meet current regulatory compliance standards?

A: The TA7267BP(O), TA7291FG(O,EL), and TA7291SG(O,J) are all RoHS compliant active products. The LB1830M-TE-L-E is obsolete with unspecified RoHS status. Substitute parts provide regulatory alignment for new designs and ongoing production.
